ROLL FOR ROLLING-MILLS.

I Specification'of Letters Patent.

Patented Dec. 29, 190

Application filed May 7, 1907. Serial No 372,378.

To all whom it may concern:

Be it known that LEVAN WILLIAMS, a citizen of the United States of America, residing at New (-astle, in the county of Lawrence .and State of Pennsylvania, have invented certain new and useful Improvements-in Rolls for Rolling-Mills,- of which the following is a specification, reference being had therein to the accompanying drawing.

'lhis invention relates to rolls for rolling mills, and the invention has for its object to provide a roll that will permit of sheetslbeipg rolled in a cooler state.

Another object of this invention is to provide a strong and durable roll which will not break and cause delay.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and tllien specifically pointed out in the appended c aim.

Referring to the drawing forming part of this specification,'like numerals of reference designate corresponding parts throughout the severalviews, in which:

Figure 1 is an elevation of a roll partly in section, Fig. 2 is an elevation of the shaft or core thereof, Fig. 3 is a cross sectional view of the roll.

To put my invention into practice, I con-.-

, struct a roll havin a cast iron body 1, a

steelshaft or core 2 aving necks 3 and Wabcorrugated or fluted, as at 6, whereby the cast iron body or shell of the roll will take a the roll.

- firm grip upon the shaft or core 2 at every point and cannot be easily broken when cast upon the hard and durable shaft or core of Should the body 1 of the roll be damaged or injured, it can be removed and another body cast upon the shaft or core 2.

It will be apparent from the illustration of my invention that I have devised a strong and durable roll which will facilitate the operation of rolling.

Such variations in the size and minor details of construction, as are permissibleby theappended claim, may be resorted to without departing from the spirit and scope of the invention.

What I claim and desire to secure by Letters r atent, 1s

A roll comprising a steel core having necks adjacent each end of greater diameter than the body of the core, a body cast on the core and having its ends abutting said necks, equally spaced longitudinally extending flutes arranged on the periphery of said core and terminating at the'necks of the core, the

said flutes. being substantially V-shapedin cross section to form'V-shaped grooves between the flutes to receive the material of which the body portion is formed while the flutes project into said material whereby the body gri s the core at all points throughout the perip cry of the latter.

In testimony whereof I aifix my signature in the presence of two witnesses.

EVAN WILLIAMS.
